The present invention concerns a method of providing communication over a mobile communication network (1) and components for providing communication over the communication network (1). The network (1) comprises two or more fixed nodes (2a, 2b) each operating a fixed radio cell (3a, 3b) for serving one or more user equipments (4) via a first radio interface (5a, 5b). Each of these fixed radio cells (3a, 3b) is identified by a physical cell ID (6a, 6b) selected out of a set of N physical cell IDs. In addition, the network (1) comprises one or more mobile relay nodes (7) served by the one or more fixed nodes (2a, 2b) via a second radio interface (8a, 8b). The mobile relay nodes (7) each operate a mobile radio cell (9) for serving one or more user equipments (4) via a third radio interface (10). Each of these mobile radio cells (9) is identified by a physical cell ID (6c) selected out of the set of N physical cell IDs. The method comprises the step of dynamically assigning a physical cell ID (6c) of the set of N physical cell IDs to the one or more mobile radio cells (9).
A method of providing communication over a mobile communication network comprising two or more fixed nodes each operating a fixed radio cell for serving one or more user equipments via a first radio interface, wherein each of the fixed radio cells is identified by a physical cell ID, selected out of a set of N physical cell IDs, and one or more mobile relay nodes served by the two or more fixed nodes via a second radio interface, the one or more mobile relay nodes each operating a mobile radio cell for serving one or more user equipments via a third radio interface, wherein each of the mobile radio cells is identified by a physical cell ID selected out of the set of N physical cell IDs, the method comprising dynamically assigning a physical cell ID of the set of N physical cell IDs to the one or more mobile radio cells.
A fixed node comprising a first communication unit adapted to operate a fixed radio cell for serving one or more user equipments via a first radio interface, the fixed radio cell being identified by a physical cell ID selected out of a set of N physical cell IDs, a second communication unit adapted to serve one or more mobile relay nodes via a second radio interface and a control unit adapted to dynamically assign a physical cell ID of the set of N physical cell IDs to the one or more mobile radio cells.
A mobile relay node comprising a first communication unit adapted to operate a mobile radio cell for serving one or more user equipments via a third radio interface, wherein the mobile radio cell is identified by a physical cell ID selected out of a set of N physical cell IDs, a second communication unit adapted to communicate via a second radio interface with one or more fixed nodes each operating a fixed radio cell for serving one or more user equipments via a first radio interface, wherein each of the fixed radio cells is identified by a physical cell ID selected out of the set of N physical cell IDs, and a control unit adapted—on assignment of a physical cell ID of the set of N physical cell IDs as new physical cell ID of the mobile radio cell—to switch from an old physical cell ID to the new physical cell ID.
